he had never been on an airplane or a high-speed train, but he was passionate about building rockets. he lacked fuel for the rocket model to launch, so he extracted it from the corner of the pigpen in his hometown. he lacked money to buy raw materials, so he borrowed money from his classmates 100 yuan or 50 yuan at a time...
recently, zhang shijie, a senior high school student from xinshao county no. 2 middle school in hunan province, has become popular online. this teenager living in a rural area of xinshao county has had a dream of building a rocket since junior high school. he used online resources such as short video platforms to teach himself how to make rocket models. from modeling to making fuel, from making a launch platform to 3d printing, he overcame many difficulties and launched his rocket model into the sky, with the highest altitude reaching 400 meters.
zhang shijie is a 17-year-old high school student from chishuipo village, pingshang town, xinshao county, hunan province. he is a real rocket fan. in the eyes of his father zhang songzhong, zhang shijie has always been a hands-on kid. other kids like to play with mobile phones, but he likes to tinker with gadgets. others play with toys, but zhang shijie likes to take them apart and put them back together.
when he was in the second year of junior high school, he watched the live broadcast of the core module of the tianhe space station with his father. the scene of the rocket launch shocked zhang shijie. "at that time, i had an idea: could i build a rocket myself?" zhang shijie said.
after watching many videos, he found that it was not a simple matter to actually build a rocket model to launch. first, you need to design a model, manufacture it, and solve problems such as fuel, which involves a lot of computer software, such as modeling software, etc. zhang shijie, aware of the difficulties, decided to tackle the problem bit by bit. he took the laptop left to him by his sister and began to look for various resources on the internet to understand the principles of rocket launch, and downloaded various learning materials on the science and technology innovation forum. at the same time, he also met some netizens with the same interests on it and asked them for advice. not knowing how to model and design software, he found video courses on the internet and began to learn little by little.
after entering high school, he did not stop his pursuit of rocket research. he taught himself drawing software and began to draw metal engines independently. in order to make the designed engine into a physical entity, he began to look for merchants who could perform 3d printing on second-hand trading platforms. after receiving the finished product, zhang shijie immediately began to experiment on the self-made slide rail and found that the thrust of the engine he made was not strong. he posted the design on the forum and received a lot of suggestions. after that, he made many improvements and gradually achieved a relatively satisfactory effect. after solving problems such as the launch pad and parachute recovery programming, he finally completed a relatively successful test flight in june last year.
zhang shijie believes that rocket research sometimes takes up some time for study, but overall it promotes learning. for example, he can apply textbook knowledge to practice. for example, he didn't know how high his rocket model flew before, but after learning high school physics and kinematics, he can calculate it by watching the landing time in the video. at present, the rocket model he made has flown more than 400 meters.
on september 1, zhang shijie started a new semester and his senior year in high school. his goal is to be admitted to an aviation college. "i hope that one day i can actually send a rocket i made into space," zhang shijie said.
